The floor plan of the current castle dates from the time of the widow of Willem I van der Marck Lumey (1485). This castle was renovated several times over the centuries and today has a neoclassical appearance. As far as is known, De Burg Castle is the oldest castle in Lummen. The castle was first mentioned in 1203 when Count Lodewijk II from Loons donated the castle, together with the allodium Lummen, to the prince-bishopric of Liège, to get it back as a fief. It was a diplomatic tool during the Loonse War. The most famous owner of De Burg was Willem II van der Marck Lumey, a notorious water beggar nicknamed "Lumey", who captured Den Briel for Willem de Zwijger, Prince of Orange. In 1837, the Stevoort jenever distiller Laurens Renier Palmers (1765-1839) bought the domain from the Duchess of Arenberg. Palmers and his wife Maria Theresia de Borman (1779-1844) were large landowners and also owned the water mills of Lummen, Terlaemen Castle with a farm and three water mills in Zolder, Stevoort Castle and a dozen farms in Stevoort and a house on the Wood market in Hasselt. Through the marriage of Catharina Palmers (1809-1891) to Henri Gerard Briers (1791-1873), De Burg came into the possession of the Hasselt Briers family. As a memorial stone in the gatehouse states, De Burg Castle was the residence of Briers' grandson, the French-speaking writer Georges Virres, pseudonym of Henry Briers de Lumey (1869-1946), Limburg provincial councilor, mayor of Lummen, member of the Royal Commission for Monuments and Sites and of the Académie royale de langue et de littérature françaises de Belgique. The castle is currently still inhabited by the Briers de Lumey family.
